Gravity pressure-bearing uplift tree-root-shaped pile foundation
The invention belongs to the technical field of building foundation engineering, and provides a gravity pressure-bearing anti-pulling tree-root-shaped pile foundation which comprises a pile group and a bearing platform, the pile group is composed of a plurality of self-bending steel piles or formed by mixing the self-bending steel piles with straight piles, and the self-bending steel piles are circumferentially distributed with the center of the bearing platform as the circle center; the bearing platform is made of reinforced concrete, the tops of the pile groups are connected into a whole, and a pile foundation similar to a tree root shape is formed. According to the pile foundation, through combination of a bearing platform and a pile group, foundation soil within the contact range of the pile group is combined into a gravity whole, and meanwhile the gravity pressure bearing function and the gravity anti-pulling function are achieved; the self-bending steel pile is provided with guide retaining teeth, so that the friction anti-pulling effect is enhanced. The pile foundation is low in pile manufacturing cost, automatic bending is achieved in the pile entering process, the construction cost is low, the mass of related reinforced concrete is greatly reduced, and the foundation engineering construction cost can be greatly reduced.
本发明属于建筑基础工程技术领域，提出了一种重力承压抗拔树根形桩基础，包括桩群和承台，桩群采用多根自弯曲钢桩组成或与直桩混合组成，多根自弯曲钢桩以承台中心为圆心，圆周分布；承台为钢筋砼，把桩群顶部联结成整体，形成类似树根形态的桩基础；所述桩基础通过承台与桩群的结合，将桩群触及范围内的地基土结合成一个重力整体，同时具有重力承压和重力抗拔作用；所述自弯曲钢桩具有导向止退齿，增强了摩擦抗拔作用。本发明所述桩基础的制桩成本低廉，进桩过程自动弯曲，施工成本低，相关钢筋砼的体量减少很多，可大幅度降低基础工程建设成本。
